An ex-convict who police have labeled as "extremely violent" and an "imminent public threat" is on the loose, police said on Monday.

Frank Edward Edmonds, 40, who also goes by Russell Robinson and Dee Robinson, was released from UCLA Harbor General Mental Health Facility on May 6, said Capt. James Madia, with the Inglewood Police Department.

According to police, while there, Edmonds allegedly made several disturbing comments to staff that he was thinking about killing school children and then ending his life in a suicide-by-cop scenario.

Edmonds has a long criminal history, including assault with a deadly weapon, resisting arrest and a pending battery case, according to authorities.

Police could not comment on the circumstances of Edmonds’ stay at UCLA Harbor General, nor could the hospital, but Edmonds may have checked himself into the facility or may have been brought there. He was released because he no longer met the county requirements to stay there, according to police.

"We don't know what the circumstances of his release were, but we were notified as a courtesy from Los Angeles County Public Health that we should know about it," Madia said.

Police have been looking for Edmonds since May 7. He is believed to be a resident of Inglewood with ties to the Compton area.
